Teachers never teach this kinda stuffs. They be like let's start they make a program that's it
and there is no explanation.

[m.a.diallo]

Please explain to me better why cout displays 6 even even you give the value of 1000 to children or slices.
It doesn’t override 6

[misty]

Starting this journey tonight! So far I love your videos and appreciate your teaching style. I can’t wait to see how much I know after even 50+ videos.

[kyzer_wilhelm]

Im having so much fun learning c++, thanks for the great tutorials

[cerium]

I LOVE your content you make it SUPER easy to understand programming!

The reason you don't use quotes for cout << slices; is because the quotes would make it a string

[samuelfischer]

For everyone watching this tutorial on a mac you can use the terminal command without the parenthesis (g++ YOUR_FILE_NAME.cpp; ./a.out) to run everything in one command

I found this very int-eresting; thanks for sharing!

[TheDarkKRoo]

Thank you for making these. I really appreciate it.

It would be interesting why one has to set a type for each variable and how it is represented in memory. To do this you would have to introduce the concept of the binary system. Also you could say that an uninitialized variable has the value that is in this part of the computer's memory at this time. So it can be different each time you start the program. Just as a hint because it happens that someone tries to access a variable which hasn't been initialized before which will likely cause errors.

Thanks very much for your clear presentation. My question is; How can I declare, initialize and assign the following integers 20;30;24;25 as the marks of my students, for instance if I was a lecturer?

turning children into slices

[mashalabouzour]

Which of the variables is not initialized?
int age = 18;

double GPA = 3.25;

char letterGrade= ‘A’;

bool done = false;

int age = 18, length, width = 5;

[DoraKage]

to clarify:

int slices;
slices = 5 + 1;
int children = slices;

slices = 1000;

returns 6


BUT:

int slices;
slices = 5 + 1;
slices = 1000;

int children = slices;

written in this way will the function return 1000?

[Koto-Sama]

is int slices = 5; the same as int slices(5); ?

[UpcycleElectronics]

I came across one conundrum of a line of cpp to run past you.

*virtual void* OnUpdate( *uint_32_t* deltaTime);

What the heck is "virtual void" and how does anything with "void" have an operation associated? I thought "void" specifically means return nothing.
I came across this while trying to figure out how someone else's library works for use with a rotary encoder and Arduino. This was in the library's header source code.

[garyjoy]

I have a question,
int main ( )
the same as
int variable
(both "int" the same)

[krish-utde]

watched. How can slices have two different integers??

[dubs]

Is it better to initialize variables, that aren't set a value as soon as they're declared, to a value like 0, 0f, or and empty string (depending on the type)? Sometimes it's hard to build good habits with small programs, as it's easier to keep track of everything.. didn't know if a value you should placed in variables to act as a placeholder for ease of not hitting errors down the road. Does it matter?
